WILLIAM LOREN DAVIS, OF CHICAGO; ILLINOIS.

CINGH-BUCKLE.

messes.

T 0 all whom it may concern:

. Be it known that I, lVILLIAM LOREN DAVIS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Cinch-Buckles, of which the following is a specification.

This invention has reference generally to improvements in that class of inventions known as buckles, buttons and clasps, and

more particularly relates to a cinch buckle.

It is the principal aim and object of the present invention to provide a device of .to engaging a strap in the latter for looking the movable frameto consequently prevent accidental disengagement of the strap.

Among the other aims and objects of this invention may be recited the provision of a device of the character described .with a view .to compactness, and. in which the number-of parts are few, the construction simple andthe cost of production low and the efficiency high.

Other improvements and novel details in the construction and arrangement of the various parts of the apparatus will be brought out more in detail in the description to follow, which for a clear understanding of the invention should be considered in connection with the accompanying drawings forming a part hereof, and wherein 1s dlS 7 closed for the purpose of illustration a convenient and satisfactory embodiment of the invention. It is to be noted in this connection that minor changes'in the construction and arrangement of parts may be made without departing from the principle of operation of the various parts.

The invention is clearly illustrated in the accompanying drawings, in which 7 Figure 1 is a top plan view of the device.

Fig. 2 is a section taken on line 2-2 of Fig. 1.

after appear.

v Specification of Letters Patent. Patentgd F 15 1921 Application filed October 8, 1918.

Serial No. 257,331.

accompanying drawings there is illustrated a strap 5 one end of which is attached to the buckle generally designated 6 while the free portion of the strap is removably engaged in the buckle.

In the present instance the improved buckle consists of a main rectangular looped frame 9 connected near its upper portion by means of a relatively wide cross bar 10 which isintegral with the opposite sides of the loop and provided with spaced vertical slotsll for a purpose that will herein- The lower end of the main frame is constructed in the form .of a rod 12, the ends of which are riveted to the outer ends of the side of the frame as at 13 fora purpose that will hereinafter become apparent. The opposite sides of the frame are also provided with" opposed vertical openings 14 at points near the lower ends, also for a purpose that will hereinafter become apparent. A substantially inverted U- shapedsecondary metallic -frame 15 is now employedand has projecting: from opposite points on its sides trunnions 16 which are swingable in the openings 14 preparatory to the fastening of the rod 12 which forms a part of the main frame. The intermediate portion 17 of the secondary frame is also formed with an opening 18 near the upper end of the frame for a purpose that will presently appear, while projecting from the lower edge of the intermediate portion 17 is a finger piece 19. The sides of the secondary frame are formed with opposed vertical slots 18 in which are slidably and rotatably engaged the trunnions of a roller 19 rectangular in cross section, the purpose of which will become apparent.

In order to lock the secondary frame within the main frame subsequent to the passing of the strap over the lower portion of the secondary frame and beneath the rod 12 at the lower end of the main frame an improved catch indicated in its entirety by on the cross bar 10.

In use, assuming that the parts have been assembledin a manner described and as illustrated in the drawings the free portion of the strap 5 is passed beneath the main frame and engaged over the roller 19' in the sec ondary frame, while the free portion thereof is finally passed beneath the rod 12 of the main frame so as to lie between this rod and the roller 19' which acts to clamp the strap.

The secondary frame is now swung inwardly whereupon the catch is slid downwardly so that the lip or flanged end 23 thereof will engage the upper portion of the frame so as to lock the secondary frame and consequently prevent accidental disengagement of the strap 5 from position.

What is claimed is:

1. A buckle of the character described in- 1 eluding a main frame, a secondary frame swingably mounted therein, a roller substantially oval "in cross section swingably and slidably mounted in the secondary frame and adapted to be engaged by a strap, said roller being subsequently slid to clamp the strap against the main frame, and a catch consisting of a plate like body 'slidably mounted on the main frame, and a lip on one end of the body for engaging the secondary frame to lock the movable frame against movement. I i

2. A buckle of the character described ineluding a main rectangular frame, a cross bar connecting the side of the frame near one end thereof and formed with spaced slots, the sides of the frame being provided with opposed openings near the opposite end, a secondary frame, opposed trunnions proj ecting from thesides thereof and near one end for engagement in the openings in the main frame for swingably supporting the secondary frame, a roller substantially oval in cross section slidably and rotatably mounted in the sides of the secondary frame and adapted to be engaged by a strap, said roller being slid subsequently to clamp said strap against the main frame, a catch consisting of a plate like body formed with a lip, andmeans anchored in'the plate like body and operable in the 'slots in the cross bar for slidably connecting the plate like body to the cross bar to permit of the slid ing of the catch to engage the secondary frame to latch the latter against movement, v 3. A buckle of the-character described embodying a main frame forengagement at one end with a strap, the said frame being formed at the other end with a transversely disposed rod, a secondary frame pivotally mounted within-the main frame, a roller substantially oval incross sectionand pivotally mounted in the secondaryframe adjacent the said 'rod thereof, the said main frame being formed with a'transversely disposed bar adjacent that end connecting with the strap, and a latch carried by the said transversely disposed bar andengageable with the secondary frame to preclude its swing ng other than in one directiomwheree 'by that end of the strap opposite the one connected with the main frame may be passed around the said rollerand underneath the said rod of the main frame to have i this end of the 'strap secured to the buckle as herein shown and specified;

In testimony whereof'I ailix my signature.

WILLIAM, LOBEN DAVIS.
